Empty array - Cyber123 - 30.01.2019

How to check if the integer array is empty without additional variable?

Re: Empty array - Kaliber - 30.01.2019

Well, what values should it handle?

If it can handle every value, then you need a second variable.

Re: Empty array - Cyber123 - 30.01.2019

I want to handle every value in array, thanks

An array can never be empty even if all the values are zero as zero is still a value! Your question makes no sense really. Maybe you want to check if integer array is null? All values 0? How the heck is anyone supposed to know?

Because i tried with additional variable and can't get what I want.

PHP код:



#include <a_samp>

#include <streamer>

#include <sscanf2>

#include <ColAndreas>

#include <zcmd>

#include <YSI_Core\y_utils>

#include <YSI_Coding\y_timers>


new Timer:timer1;

new Grass[5];

new br=0;


new scfmString[250];

#define SCM SendClientMessage

#define SCFM(%1,%2,%3) format(scfmString,sizeof(scfmString),%3), SCM(%1,%2,scfmString)


public OnFilterScriptInit()

{

    CA_Init();

    return 1;

}


public OnFilterScriptExit()

{

    return 1;

}


CMD:as(playerid, params[], help) 

{

    for(new i=0; i<5; i++)

    {

        new Float:randx = RandomFloat(109.2241-92.6121)+92.6121;   

        new Float:randy = RandomFloat(-71.6366-(-57.7923))+57.7923;

        new Float:z;

        CA_FindZ_For2DCoord(randx, randy, z);

        Grass[i] = CreatePlayerObject(playerid, 802, randx, randy, z+0.2, 0, 0, 0);

    }

    timer1 = repeat Tajmer(playerid);


    return 1;

}

CMD:aa(playerid, params[], help) 

{

    stop timer1;

    return 1;

}


timer Tajmer[100](playerid)

{

    new Float:x,Float:y,Float:z;

    for(new i=0; i<sizeof(Grass); i++)

    {

        GetPlayerObjectPos(playerid, Grass[i], x, y, z);

        if(IsPlayerInRangeOfPoint(playerid, 1, x, y, z))

        {

            DestroyPlayerObject(playerid, Grass[i]);

            Grass[i] = 0;

            br++;

        }


    }

    if(br >= sizeof(Grass))

    {

        SendClientMessage(playerid, -1,"No grass");

    }

    return 1;

}

I have problem with this part:

PHP код:



        if(IsPlayerInRangeOfPoint(playerid, 1, x, y, z))

        {

            DestroyPlayerObject(playerid, Grass[i]);

            Grass[i] = 0;

            br++;

        }

Sometimes do this if object is already destroyed

pawn Код:

if(Grass[i] != 0 && IsPlayerInRangeOfPoint(...))

pawn Код:

if(GetPlayerObjectPos(playerid, Grass[i], x, y, z) && IsPlayerInRangeOfPoint(...))

propably first code is better and if you want something for player it should be

Grass[playerid][i]

because if few players use /as there will be fun

Re: Empty array - Cyber123 - 31.01.2019

Thank you Jeff, I fixed it.

They would have to be right next to every piece of grass at the same time. Is that the case?

It gives me exactly what I want. It checks if all objects are destroyed.

Re: Empty array - Cyber123 - 31.01.2019

No they are not.
